(if you want to have a baby)

Apparently December 11th is the most fertile day ever as your sperm is miles better when its cold.

FACT

- December 11th named as the most fertile day of the year
- September 16th is the most popular birthday in the UK
- Scientists say that sperm quality is higher in the cold
- Christmas parties also lead to more sex

That last one is a shocker.

So....?
